Question

我想为AES算法创建SBOX，所以我想创建一个16行16列的矩阵。

我创建了一个[16，16]的二维数组，但是我不断收到有关长度为16的初始化程序的错误，我的代码有什么问题？

int[,] SBox = new int[16, 16] 
            {
            //0     1    2      3     4    5     6     7      8    9     A      B    C     D     E     F

这里出了什么问题？

如果要制作一个16行16列的矩阵。

您可以尝试使用{}包含16个int然后创建16列。

int[,] SBox = new int[16, 16]
    {

        {0x63, 0x7c, 0x77, 0x7b, 0xf2, 0x6b, 0x6f, 0xc5, 0x30, 0x01, 0x67, 0x2b, 0xfe, 0xd7, 0xab, 0x76} , //0
        {0xca, 0x82, 0xc9, 0x7d, 0xfa, 0x59, 0x47, 0xf0, 0xad, 0xd4, 0xa2, 0xaf, 0x9c, 0xa4, 0x72, 0xc0}, //1
        {0xb7, 0xfd, 0x93, 0x26, 0x36, 0x3f, 0xf7, 0xcc, 0x34, 0xa5, 0xe5, 0xf1, 0x71, 0xd8, 0x31, 0x15}, //2
        {0x04, 0xc7, 0x23, 0xc3, 0x18, 0x96, 0x05, 0x9a, 0x07, 0x12, 0x80, 0xe2, 0xeb, 0x27, 0xb2, 0x75}, //3
        {0x09, 0x83, 0x2c, 0x1a, 0x1b, 0x6e, 0x5a, 0xa0, 0x52, 0x3b, 0xd6, 0xb3, 0x29, 0xe3, 0x2f, 0x84}, //4

        {0x60, 0x81, 0x4f, 0xdc, 0x22, 0x2a, 0x90, 0x88, 0x46, 0xee, 0xb8, 0x14, 0xde, 0x5e, 0x0b, 0xdb}, //9
        {0xe0, 0x32, 0x3a, 0x0a, 0x49, 0x06, 0x24, 0x5c, 0xc2, 0xd3, 0xac, 0x62, 0x91, 0x95, 0xe4, 0x79}, //A

错误是因为您的数组定义最多只有16个项目，但是您正在分配一个包含256个项目的数组。

https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/arrays/

必须声明和分配多维数组，如下所示：

//声明并设置数组元素的值 int [，] multiDimensionalArray2 = {{1，2，3}，{4，5，6}};

长度为'16'的数组初始值设定项
